ABC transporters for a large family of proteins responsible for translocation of a variety of compounds across biological membranes. ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains.	Domain

Most functional ABC transporters are composed of at least four sub-units: two trans-membrane (TM) domains where the transport process takes place and two cytoplasmic nucleotide binding domains (NBDs) providing the energy required for active transport [1]. This entry is one of the two NBDs found at the the C-terminal domain of FbpC, ferric iron uptake transporter, from the Neisseria gonorrhoeae. The C-terminal regulatory domain adopts two OB-folds per monomer. These are similar in topology to those seen in the NBD (nucleotide binding domain) from the maltose uptake ABC transporter, MalK. However, FbpC does not open as far as MalK when ATP is removed from their respective closed structures. This difference was suggested to be due to the substantial domain swap in the regulatory domain of FbpC [2].	Domain
